FortiGate-3950B and FortiGate-3951B
The FortiGate-3950B features one NP4 processor. The 1Gb SPF interfaces, port1, port2, port3, port4, and the 10Gb SPF+ interfaces, port5, port6, share connections to one NP4 processor. The FortiGate-3951B is similar to the FortiGate-3950B, except it trades one FMC slot for four FSM slots. The network interfaces available on each model are identical.
You can add additional FMC interface modules. The diagram below shows a FortiGate-3950B with three modules installed: an FMC-XG2, an FMC-F20, and an FMC-C20.
• The FMC-XG2 has one SP2 processor. The 10Gb SPF+ interfaces, port1 and port2, share connections to the processor.
• The FMC-F20 has one NP4 processor and the twenty 1Gb SPF interfaces, port1 through port20, share connections to the NP4 processor.
• The FMC-C20 has one NP4 processor and the twenty 10/100/1000 interfaces, port1 through port20, share connections to the NP4 processor.
